if buying new and its an option and you expect to camp in heat its a no brainer.....one COULD work if conditions were optimal (parked in some shade, don't open door much , no more than 2 human heat btu units inside).....but why?... ours saw 104-110 this summer in full sun and the 2 15k units would cool to 72 and still cycle..!!...I could not imagine being comfortable in those conditions with only 1 unit....matter of fact I only have 30 amp sercive at my house and the one ac will only cool to about 76-77 inside with 95+ outside temps.....better? ...sure....comfy?...not for me..!
